Yes, but the SB-220 tune C typically arcs when the load is connected,
well after the amplifier has been tuned up. I have inadvertently tuned
my SB-220 up with the load removed. There was no arcing in the tune C,
(whose measured withstanding ability was 3600v). . . . 8700v doesn't
wash.

Congrats John F., you were right about the smoke and mirrors. Thanks for
the warning.
